Refill Paint Roller Reservoir

What happens here

Once the paint in the Smart Roller's internal reservoir is nearly depleted, indicated by less coverage on the wall and the painter's verbal cue of being 'out of paint,' the painter detaches the main roller unit from the extension pole's handle. He then inserts the intake end of the roller into a paint bucket and pushes down on the plunger. This action quickly draws fresh paint directly from the bucket into the roller's reservoir, allowing for a rapid refill without the need for a separate paint tray.

Goal: Replenish the paint supply in the roller for continued painting.
